Using Converse Statements to Prove Lines Are Parallel

Given parallel straight lines l and m in Euclidean space, the following properties are equivalent: 1. Every point on line m is located at exactly the same (minimum) distance from line l (equidistant lines). 2. Line m is in the same plane as line l but does not intersect l (recall that lines extend to infinity in either direction).
